83 A new steganographic method called STABYLO is introduced in
85 Its main advantage is to be much lighter than the so-called
86 Highly Undetectable steGO (HUGO) scheme, a well-known state of the art
87 steganographic process in the spatial domain.
88 Additionally to this effectiveness,
89 quite comparable results through noise measures like PSNR-HVS-M,
90 and weighted PSNR (wPSNR) are obtained.
91 To achieve the proposed goal, famous experimented
92 components of signal processing,
93 coding theory, and cryptography are combined together, leading to
94 a scheme that can reasonably face up-to-date steganalysers.

119 The STABYLO algorithm, whose acronym means STeganography with
120 Adaptive, Bbs, and binarY embedding at LOw cost, has been introduced
121 in this document as an efficient method having comparable, though
122 somewhat smaller, security than the well-known
123 Highly Undetectable steGO (HUGO) steganographic scheme.
124 This edge-based steganographic approach embeds a Canny
125 detection filter, the Blum-Blum-Shub cryptographically secure
126 pseudorandom number generator, together with Syndrome-Trellis Codes
127 for minimizing distortion.
128 After having introduced with details the proposed method,
129 we have evaluated it through noise measures (namely, the PSNR, PSNR-HVS-M,
130 BIQI, and weighted PSNR), we have used well-established steganalysers.
132 % Of course, other detectors like the fuzzy edge methods
133 % deserve much further attention, which is why we intend
134 % to investigate systematically all of these detectors in our next work.
137 For future work, the authors' intention is to investigate systematically
138 all the existing edge detection methods, to see if the STABYLO evaluation scores can
139 be improved by replacing Canny with another edge filter.
140 Other steganalysers than the ones used in this document will be
141 examined for the sake of completeness. Finally, the
142 systematic replacement of all the LSBs of edges by binary digits provided
143 by the BBS generator will be investigated, and the consequences of such a
144 replacement, in terms of security, will be discussed.
145 Furthermore, we plan to investigate information hiding on other models, such as high frequency for JPEG encoding.
